20 POINTS!!!!!

20. What is the exact volume of a cylinder whose diameter is 10 meters and whose height is 12 meters? Show your work.

21. What is the exact volume of a sphere whose diameter is 14 cm? Show your work.

Answer 1

20. 300π m³

21. 457 1/3 π cm³

Explanation:

20. r = 10 ÷ 2 = 5

V = 5² × 12 × π = 25 × 12π=300π m³

21. r = 14 ÷ 2 = 7

`V = (4)/(3) \pi 7x^(3)`

V = 457 1/3 π cm³
